Availability of several over-the-counter allergy tests add to confusion of partially trained caregivers. The presentreview focuses on current status of allergy testing in Indian scenario. Various in-vitro and in-vivo diagnostic modalities are available forallergy detection. Skin prick tests are useful for aero-allergies whereas oral challenge tests are best for identifying suspected foodallergies. An allergy test should be individualized based on clinical features, diagnostic efficacy, and cost-benefit analysis.
